ECTOPAASITICIDAL AGENTS CONTAINING SUBSTITUTED PHENOXY-BENZYLOXY-CARBONYL DERIVATIVES AND (THIO) PHOSPHORIC ACID ESTERS, A PROCESS FOR THEIR PREPARATION AND THEIR USE AS ECTOPARASITICIDES

摘要

A composition containing a synergistic combination of the active ingredients (1) a phenoxybenzyloxycarbonyl derivative of the general formula IMAGE in which R, R1 and R2 are selected independently and each represent hydrogen or halogen, R3 represents phenyl or substituted phenyl, Y represents hydrogen or cyano, n represents an integer from 1 to 5 and m represents an integer from 1 to 4, and (2) a (thio)phosphoric acid ester, alone or in admixture with a solid of liquid or liquefied gaseous diluent or carrier, has a powerful ectoparasiticidal action, especially against ticks.
